IMPROVEMENT IN REPAIRING CULTIVATOR-SHOVELS.

Specification forming part of Letters Patent No. 222.511, dated December 9, 1879; application filed April 21, 1879.

To all whom it may concern.-

Be it known that I, J OHN LAHR, of Secor, in the county of Woodford and State of Illinois, have invented a new and valuable Improvement in Repairing Cultivator-Shovels; and I- do hereby declare that the following is a full, clear, and exact description of the construction and operation of the'same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a face view of the repaired shovel in perspective. Fig. 2 is a plan view of the repairpoint. Fig. 3 is an edge view of the same. Fig. 4 is a back view of the shovel, showing the repair-point applied. Fig. 5 is a face view of a worn shovel in perspective. Figs. 6 and 7 are details.

This invention has relation to means for repai rin g cultivator-shovi-ls,as herein after sho Wu and described.

In the accompanying drawings, the letter A designates an old cultivator-shovel, whereof the point portion a is worn down and rounded so as to be of little use. This point portion,

although rounded form, is designed to be refitted and extended in proper or normal form, so as to serve its purpose as well as, if not better than, a new shovel, and to this end a repair-point, B, is provided. This is of angular shape, and beveled from its front edge, It is preferably formed by means of a beveled blank, 0, tapering toward each of its ends and cleft at its middle or wider portion from the rear edge nearly to the front edge. This blank is bent at the cleft 6?, so that the narrow connecting-portion 0 forms the apex, and the portions or wings h, on each side of the cleft, are lapped one on the other, as shown. This angular pointthus formed is welded to the under side of the wornpoint portion of the shovel A, and drawn out into shape and properly ground, forming a shovel, D, of superior character and durability, because of the toughness and body of its new point portion.

By cleaving the blank centrally and lapping its wings, thus formed, the blank pointis adapted to be readily and quickly adjusted to the worn plow or cultivator point, and this cleaving and lapping of the parts also enters into the formation of the new point.

Having thus described my invention,what

I claim as new, and desire to secure by Letters Patent, is-

The improvement in the art of repairingcultivator-shovels, which consists in cleaving the beveled blank centrally toward its front, lap ping its wings one on the other, and welding the wings together at the same time that the blank so formed is welded to the worn-out cultivator-shovel, as described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

JOHN LAHR.
